Abstract
An energy system consists of a gas turbine engine having a power turbine which is arranged to drive a load, the exhaust from the power turbine passes to a further turbine which is arranged to drive a compressor, the exhaust from the further turbine passes to atmosphere via the compressor and a combined cooler and scrubber in which water is heated and sulphur is removed from the hot exhaust gas. The combined cooler and scrubber consists of a bed of flints through which the hot exhaust gas flows and a condenser arranged to receive a supply of relatively cool water, the resulting hot water being stored in a hot water store. The bed of flints also receives a supply of water to which calcium carbonate and manganese sulphate has been added so that sulphur in the form of calcium sulphate is removed from the exhaust gas.
